Abstract

The invention relates to continuous-type microwave hot air combined drying equipment which comprises a material lifting device, a lower hopper auxiliary device, an upper layer conveyer belt, a lower layer conveyer belt, a microwave case, a humidity-discharging device, a hot-air device; the upper layer conveyer belt and the lower layer conveyer belt are arranged in the microwave case in parallel; the microwave case is internally provided with a microwave tube; a discharge port of the material lifting device is arranged above the lower hopper auxiliary device which is positioned above the loading end of the upper layer conveyer belt; the discharge end of the upper layer conveyer belt is provided with a guide plate which is positioned above the loading end of the under layer conveyer belt; a humidity-discharging device is arranged on the top of the microwave case; and the hot-air device is arranged at the bottom of the microwave case. The equipment achieves the effect of energy-saving and high efficient by adopting the structure.

Description

technical field [0001] The invention relates to a microwave drying and sterilizing equipment for tanning sludge, in particular to a continuous microwave hot air combined drying equipment. Background technique [0002] The drying methods for tannery sludge in the prior art mainly include natural drying method and vacuum drying method. The advantages of natural drying method are low investment and low energy consumption. It is very practical for small tanneries located in rural areas and dry and sunny areas, but its disadvantages are: low dehydration efficiency, long drying cycle, large space occupation, It has an odor and attracts insects, etc., and when the sludge is laid in a thick thickness, it cannot be dried satisfactorily. In addition, this drying method is also easily restricted by natural climate conditions. Conventional vacuum drying equipment is used to dry the sludge. Since it is very difficult to transfer heat through convection in a vacuum, it can only be conduc...
